A hearing will be held today on whether bail should be lowered for one of the men accused of beating San Francisco Giants fan Bryan Stow in the parking lot of Dodger Stadium on opening day.

Louie Sanchez, 29, and Marvin Norwood, 30, both of Rialto, were arrested July 21 and charged the next day in connection with the March 31 attack. Each is being held in lieu of $500,000 bail.

At a court hearing last week, Los Angeles Superior Court judge rejected a defense motion to reduce bail for Norwood, citing “the seriousness of the charges” and indications he would be a threat to public safety if released.

Attorneys for Sanchez will make a similar bail-reduction request today.

Prosecutors contend in court papers that the high bail amounts are justified since the severity of the injuries to Stow more closely resembled “homicide than an ordinary assault.” Sanchez and Norwood are both scheduled to be arraigned Aug. 10.

According to court papers, police recovered “five firearms, including an AR 15 assault rifle” during a search of Norwood’s home. Prosecutors also say that Sanchez “told witnesses not to provide information about the crime.”

Sanchez’s attorney, Gilbert Quinones, said outside court last week that his client was a Dodgers fan who had attended the opening day game with “his brother-in-law, his sister and his child.” He said Sanchez works as a supervisor in the auto-detailing department of a Fontana vehicle auction company.

Sanchez “doesn’t seem like the type of individual who would do this,” Quinones said, declining to describe what his client may have told him about the events of March 31.

Norwood’s lawyer, Lee Rosen, said his client worked as a carpenter.

Both men are charged with mayhem, assault by means likely to produce great bodily injury and battery with serious bodily injury, all felonies, according to the District Attorney’s Office. Sanchez is also charged with two misdemeanor counts of battery stemming from another alleged run-in the same day, when he allegedly attacked another man and woman, according to the criminal complaint.

The charging document refers to injuries that caused Stow “to become comatose due to brain injury and to suffer paralysis.”

Police said Stow was attacked solely because he was wearing Giants apparel while his attackers and the female getaway driver were wearing Dodgers gear.

Stow, a 42-year-old Santa Cruz paramedic and a father of two, remains hospitalized at San Francisco General Hospital.

An initial suspect in the case, 31-year-old Giovanni Ramirez, was arrested May 22 but was never charged in the Stow beating. He has now been cleared of any involvement, even though

Los Angeles police Chief Charlie Beck initially expressed confidence the right man had been arrested. Ramirez is now imprisoned in San Diego on a violation of his parole stemming from another case, but his attorneys are petitioning for his release.

Stow’s assailants allegedly fled in a car driven by a woman. Dorene Virginia Sanchez, 31, the sister of Louie Sanchez and the wife or girlfriend of Norwood, was arrested on suspicion of being an accessory, but she was released on $50,000 bail. She has not been charged, but has a tentative court date of Aug. 19, according to Los Angeles County Jail records.

According to various media reports, Sanchez may have testified against her brother and Norwood before a county grand jury.

Sanchez faces a maximum of nine years in prison, while Norwood faces up to eight years behind bars, according to prosecutors.
